The screenshot obtained by Android Police explains how stock of the device is showing up at retail locations, but "must not go on sale before 9am on Wednesday."

Just yesterday, a Twitter user posted an NDA-smashing photo of "a box of Chromecasts," apparently from a Curry's or PC World store. Unsurprisingly, the picture has since been deleted.

Google recently updated the Chromecast Android app with support for over 50 languages, seemingly signalling that the international roll-out is imminent.

Worth the wait?

The update comes after the retail source strongly hinted the device would be on sale for £30. It costs $35 (around £21) in the United States. Brits will seemingly have to pay a little more for the privilege of owning a Chromecast dongle.
